Year atMonthDay() method in Java

The atMonthDay(MonthDay) method of Year class in Java combines the current year object with a month-day object passed as parameter to it to create a LocalDate object.

Syntax:

public LocalDate atMonthDay(MonthDay monthDay)

Parameter: This method accepts a single parameter monthDay. It is the MonthDay object which specifies a month-day to use. It takes a valid MonthDay object and cannot be NULL.



Return Value: It returns a LocalDate object formed by the current year object and a valid MonthDate object passed as parameter to the function.

Note: If the current year is not a leap year and the MonthDay object passed as parameter specifies “29th February”, it will be automatically rounded to “28th February” in the resulting LocalDate object.
